Question

我对此完全陌生，想要运行单个查询并输出cdv文件

格式为：

CODE  |  Quant
46  |  4
57  |  10
810 |  2

查询每个代码：

select COUNT(*) from OrderItemInfo
where PriceCode = '46'
and PrepareDateTime between '2013-01-01' and '2013-12-31'

价格代码将从46,57,810等变化

我不确定它是否可以作为查询完成，或者我是否需要采用不同的方式来执行此操作，脚本或其他内容。

Answer 1

不知道你使用的SQL的哪种风格可能有些偏差，但我相信你想要一个Group By

SELECT PriceCode, COUNT(*)
FROM orderItemInfo
WHERE PrepareDateTime between '2013-01-01' and '2013-12-31'
GROUP BY PriceCode

Answer 2

按PriceCode添加一个组，然后选择价格代码并计算（*）

 select COUNT(*),PriceCode from     OrderItemInfo where PriceCode = '46' and     PrepareDateTime between '2013-01-01' and     '2013-12-31'
group by PriceCode

Answer 3

SELECT PriceCode, COUNT(*) 
FROM OrderItemInfo
WHERE PrepareDateTime between '2013-01-01' and '2013-12-31'
GROUP BY PriceCode
ORDER BY PriceCode
